yenta_socket: ENE CB712 CardBus bridge needs special treatment with Echo Audio Indigo soundcards 

Indigos are well known for distortions when running on some buggy ENE
controllers.  There is a workaround in the yenta driver, but for some
reason it isn't activated on CB712.  However, I own a laptop with such
chip and it seems that it also is affected - I can clearly hear occasional
cracks, especially under heavy network load, and in Windows XP the card is
completely unusable.

This simple change fixed things for me.
